Some Problems with the Ferrier/Hirschberg Bootstrap Idea
Simar, Léopold; Wilson, Paul - In: Journal of Productivity Analysis 11 (1999) 1, pp. 67-80
This paper demonstrates that the bootstrap procedure suggested by Ferrier and Hirschberg (1997) gives inconsistent estimates. A very simple example is given to illustrate the statistical issues underlying nonparametric efficiency measurement and the problems with the Ferrier/Hirschberg approach,...
